There are many types of flange gasket,their materials and use conditions are different. Materials of flange gasket: Natural rubber and synthetic rubber, such as natural rubber, neoprene rubber, styrene butadiene rubber, nitrile rubber, ethylene propylene rubber, fluorine rubber, etc. Asbestos r ...

What are flange assembly? 1. Before assembling the flange, the flange surface must be cleaned, especially the sealing surface. 2.When assembling the slip on flange, insert the pipe end into two thirds of the inside diameter of the flange, and then the flange and the pipe are spot welded in one p ...

The loose sleeve flange of the welding ring is a movable flange piece, which is usually matched with the water supply and drainage fittings. When the factory leaves the factory, both ends of the telescopic joint have a piece of flange, which is directly connected with the pipe and equipment in t ...

An orifice flange is used in combination with orifice meters to measure the flow rate of oil, gas and other liquids conveyed by the pipeline. Pairs of pressure tappings are machined onto the orifice flange, making separate tappings on the pipe wall unnecessary. Two orifice flanges with bolts and ...

The welding of large flanges is a part that connects the pipe to the pipe. It is connected to the pipe end and sealed with a gasket. The welding of large flanges is also called welding flange. The welding flange has holes and bolts make the two flanges tightly connected. It is a disc-shaped part ...

Hebei Haihao Group has finished an order of ASTM A182 Gr F347 weld neck flange(WN flange) order from Russia. Thus let’s learn more about this material. Grade 347 is an austenitic steel alloy with the addition of a stabilizing element i.e. Niobium. Niobium, when added to stainless steel all ...

Socket welded flange (SW Flange) is a popular type of pipe flange originally developed for small-size high pressure piping.Socket welded flanges are made similar to slip on flanges.However, the socket welded flange of the inner pocket allows for a smooth hole and better fluid flow.During interna ...

The finish on the flange face requires a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal, which is measured as an Arithmetical Average Roughness Height (AARH) and determined by the standard used.For example,in ANSI B16.5 and EN1092-1 s ...

The sealing structure of the high-pressure flange lens pad is as follows: the sealing surfaces on both sides of the lens pad are spherical surfaces, the beveled surface of the tube end contacts the tapered sealing surface, and the angle between the tube end and the lens pad is about 20 degrees. ...

Chamfering,as the name implies,is to pour out the angle,generally 90 degrees into 45 degrees. Chamfering is a term used in mechanical engineering. For example, when drilling on a board, the hole wall and the board surface are 90 degrees right angle after completion. Chamfering is to make a small ...

Both blind flanges and spectacle blind flanges are used to isolate a section of pipe or equipment when they need to be inspected or removed from a piping system.But they are different.Let’s see what’s the difference between them? Blind flange and spectacle blind flange have different ...

Sometimes we call lap joint flange as loose flange which used in conjunction with a “Lap Joint Stub End”.Their dimension is same as other flanges. They are widely used in oil field, offshore, water system,shipbuilding,natural gas,electric power,and pipe projects. Lap joint flange or ...
